前言

 在ubuntu下,下载了一个JDK1.8 api中文文档,格式为.chm, 系统默认情况下是不支持直接打开的,需要自己安装一下软件, 推荐Kchmviewer软件

软件简介

 Kchmviewer 是一款不错的开源软件，你可以使用它在Linux系统下阅读 CHM格式 的电子书。KchmViewer 作为一款使用Qt开发的程序，与KDE桌面环境整合得很好。从语言兼容性上看，KchmViewer 支持包括中文、俄文等在内的多种语言。它不像有的CHM阅读程序，仅仅支持几种很少的语言。在功能特性上，KchmViewer 具有搜索、书签、更改字体大小、浏览目录、设置代码页等。Kchmviewer 的主要优势是扩展支持非英语类语言，不同其他，它能准确地确定文件的编码，正确的显示中文，朝鲜语，日本语的帮助文档，能够正确搜索非英语的单词。

安装命令

sudo apt-get install kchmviewer

解决中文乱码

 有可能你下载的chm文件,打开后中文是乱码的,解决方法如下

菜单选项 View ---- 选择 Set encoding ---- Chinese Simpilified (GB2313) 其他中文编码也可以试试,直到解决问题.

正常显示图如下:

3: 上传jdk安装到到linux服务器
推荐放到/usr/local目录下
4: 解压jdk
解压到当前文件夹：
tar -xvf jdk-8u291-linux-x64.tar.gz

5: 配置环境变量
· 安装Java：如果系统中未安装Java，可以使用以下命令来安装Java运行时环境和Java开发工具包（JDK）：
· · bashCopy Code
· · sudo apt update
sudo apt install default-jre
sudo apt install default-jdk
· · 这些命令将更新系统的软件包信息，并安装默认的Java运行时环境和JDK。
确定Java安装路径：安装Java后，需要确定Java的安装路径。可以通过运行update-alternatives --list java命令来找到Java的安装路径
用root@wannian07-PC:~# update-alternatives --list java
/usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java
root@wannian07-PC:~# gedit /etc/profile
设置Java环境变量：一旦确定了Java的安装路径，需要在终端中执行以下命令来设置Java环境变量：
设置JAVA_HOME环境变量，指向Java的安装目录。例如，如果Java安装在/usr/lib/jvm/java-版本路径下，可以在用户配置文件（如~/.bashrc或~/.zshrc）中添加以下行：export JAVA_HOME=/usr/lib/jvm/java-版本。

进入编辑状态，加入下边这段配置
export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java

#export JAVA_HOME=/usr/local/jdk1.8.0_291
export PATH= $JAVA_HOME/bin:$ PATH
export CLASSPATH=.: $JAVA_HOME/lib/dt.jar:$ JAVA_HOME/lib/tools.jar

6: 重新加载配置
source /etc/profile
7: 测试一下
